Breast hook is a shipbuilding term used to describe a horizontal piece of plate in the fore peak of a vessel. They support the stem and bow plating, an area prone to loadings of pounding and slamming. They are fit to shape on the fore, and generally curved or cut to save weight on the after side - forming a bow-like shape. Today, they are cut to shape from flat plate.
The term Breast Hook is a carry-over from wooden boat building era.
